...Dawn A. Kellett; Neil Rogers; Vicki McNicoll; Andrew Kerr; Cees van Staal Abstract Devonian and younger plutonic suites of the Appalachian orogen in Newfoundland form a curvilinear belt straddling the boundary between Ganderia and Avalonia, and exhibit a general pattern of younging to the southeast...

... zircon. These characteristics are shared with the Monian terrane of Anglesey and with Ganderia in the Appalachians, indicating probable derivation from Amazonia in West Gondwana. Silurian sandstones from the Lake District show an influx of Laurentia-derived zircon, and lack the peri-Gondwanan signal...

... the transfer of Ganderia and Avalonia from Gondwana to Laurentia, which led to closure of the Iapetus Ocean and opening of the Rheic Ocean. Ganderia, a long-lived arc terrane, separated from the paleo-Caribbean margin of Amazonia at 505 Ma with a latitudinal speed of ∼9 cm/a northward, initiating the Rheic...

... on the leading edge of Ganderia, a peri-Gondwanan microcontinent. Although the Penobscot and Victoria stages of arc-backarc development occurred in a predominantly extensional suprasubduction-zone setting, they each display a distinctly different character of magmatism and sedimentation. These stages...

...Klaus J. Schulz; David B. Stewart; Robert D. Tucker; Jeffrey C. Pollock; Robert A. Ayuso Abstract The Ellsworth terrane is one of a number of fault-bounded blocks that occur along the eastern margin of Ganderia, the western-most of the peri-Gondwanan domains in the northern Appalachians that were...

The Cadomian-type terranes, on the other hand, appear to have remained attached to Gondwana until its collision with Laurussia during the Devonian–Carboniferous Variscan orogeny.
